DETAILED DESCRIPTION

Technical solutions of the present disclosure will be further describedin detail with reference to the accompanying drawings and embodiments.

As shown in FIG. 1 , an embodiment of the present disclosure provides aninformation processing method which is applied to a first communicationdevice. The method includes:

Step S110: X sets of parameter values jointly encoding M types oftransmission parameters are sent to a second communication device, wherethe M types of transmission parameters include a beam indication and/ora quasi-co-location (QCL for short) indication parameter, where the beamindication is used for indicating a beam, the QCL indication parameteris used for indicating a parameter of the beam, and M>1.

Step S120: Y sets of parameter values are selected from the X sets ofparameter values, where X>=Y>=1.

Step S130: a selection indication is sent to the second communicationdevice based on the Y sets of parameter values, where the selectionindication is used for selecting, by the second communication device,the Y sets of parameter values from the X sets of parameter values fordata transmission.

In this embodiment, the first communication device and the secondcommunication device are two parties which can communicate with eachother. For example, the first communication device may be a basestation, a relay node or another communication device, and the secondfirst communication device may be one of various types of terminals.

The base station may include: an evolved NodeB (eNB), a next generationNodeB (gNB), a home base station, a macro base station or a small basestation. The relay node may be a wireless node for the relaytransmission, for example, a terminal or a wireless signal amplifier.

The terminal may include: a human-mounted terminal, such as a smartphone, a tablet and a wearable device; a vehicle-mounted terminalcarried in a car or other vehicles; or an Internet of Things terminal.The typical Internet of Things terminal may include: a smart home and/ora smart appliance, such as an smart water meter, an smart electric meterand the like.

In this embodiment, the first communication device sends the X sets ofparameter values jointly encoding the M types of transmission parametersto the second communication device. The M types of transmissionparameters are parameters related to beams for the data transmission. Inthis embodiment, the M types of transmission parameters may beconfigured and transmitted to the second communication device together.The M types of transmission parameters are parameters related to beams.That is, when the beam switching is performed, transmission parametersto which the switched beam corresponds needs to be changed so as toensure the transmission quality and the communication quality.

The X sets of parameter values include X sets of values jointly encodingthe M types of transmission parameters. In step S110, the X sets ofparameter values may be sent through the higher layer signaling, such asRRC signaling and/or MAC signaling. In other embodiments, the X sets ofparameter values may be sent through the physical layer signaling. Forexample, part of parameter values in the X sets of parameter values issent through downlink control information (DCI for short).

In step S120, Y sets of parameter values are selected from the X sets ofparameter values. In one embodiment, the method further includes:

obtaining channel state information for communicating with the secondcommunication device and/or measurement information of a specifiedreference signal. The measurement information reflects which beams areused by the first communication device and the second communicationdevice to communicate with each other so as to obtain bettercommunication quality. For example, the second communication devicefeeds back measurement information of each beam to the firstcommunication device; and the first communication device selects one ormore of beams to communicate with the second communication deviceaccording to the measurement information. For example, the firstcommunication device selects several beams with the best communicationquality as currently used beams or alternative beams. According to acorrespondence between the current used beams and the X sets ofparameter values, Y sets of parameter values are selected from the Xsets of parameter values, where the Y sets of parameter valuescorrespond to the currently used beams or alternative beams. The valueof Y may be 1, 2, 3 or other values. For some states with multipleconnections, the value of Y may be greater than or equal to 2.

In some embodiments, when it is determined that Y sets of parametervalues are selected, the Y sets of parameter values are used tocommunicate with the second communication device so as to ensure thecommunication quality. In this embodiment of the present disclosure,beams to which the Y sets of parameter values correspond are used toperform the data transmission.

For example, before and after the beams used by the two parties forcommunication are switched, some changes may occur: changes in the beamwidth, changes in the beam direction, changes in the beam transmittingpanel and changes in the beam transmitting node, and these changes maycorrespondingly change the optimum transmission parameters for obtainingbetter communication quality.

Changes in the transmitting beam, including the change in the beamwidth, the changes in the beam direction, the changes in the beamtransmitting panel and the changes in the beam transmitting node, maychange channel characteristics of the beam transmission. For example,the channel characteristics of the beam transmission may include one ormore of the following: the multipath number, the multipath direction,the multipath-time delay, the multipath power. Due to changes in thechannel characteristics, the following parameters may require to bechanged: a precoding resource bundling granularity of a physicalresource block (PRB), demodulation reference signal (DMRS)configuration, an uplink sub-band size (UL SB size) and/or trackingreference signal (TRS) configuration.

Changes in the beam transmitting panel and the beam transmitting nodemay cause changes in the crystal oscillator, which may cause the changein the phase noise. Therefore, a Phase Tracking Reference Signal (PTRS)configuration and the TRS configuration need to be changedcorrespondingly.

Changes in the beam width, changes in the beam direction, changes in thebeam transmitting panel and changes in the beam transmitting node maycause changes in the transmitting antenna configuration and channelrank, which may affect the configuration of the max transmission layernumber.

For the uplink transmission, changes in the transmitting beam, includingchanges in the beam width, changes in the beam direction and changes inthe beam transmitting panel, may cause changes in the channelcharacteristics, which may cause the change in the optimum codebooksubset.

Changes in the beam width, changes in the beam transmitting panel,changes in the beam transmitting node, changes in the beam gain, changesin the beam path loss and changes in the beam interference variation maycause changes in the signal to interference noise ratio (SINR) interval,which may affect the distribution of the modulation and coding scheme(MCS).

In addition, the changes in the beam transmitting node may also cause areconfiguration requirement of a hybrid automatic retransmission request(HARQ) parameter, a resource allocation (RA) parameter, a bandwidth part(BWP) parameter and a random access response (RAR) parameter.

In the HARQ parameter, the number of coding block groups (CBG) is mainlyaffected and the number of coding block groups (CBG) suitable todifferent beam transmitting nodes is different.

The RA parameter is a resource allocation parameter and mainly includesthe resource allocation type, minimum unit of the resource allocationand other parameters. Different transmission nodes may have differentoptimum RA parameters.

The BWP parameter indicates the bandwidth part, and differenttransmission nodes may have different bandwidths and different BWPpartition.

FIG. 3 is a schematic diagram illustrating the transmission of differenttransmission parameters by using different signalings. For example, abeam indication or a QCL indication is transmitted by using thesignaling 1 which may be RRC signaling, MAC signaling or DCI signaling.A DMRS configuration parameter is transmitted by using RRC or DCIsignaling. The uplink codebook configuration parameter and the like aretransmitted by using the signaling 3 which may be the RRC signaling, MACsignaling or DCI signaling. The PTPS configuration parameter and thelike are transmitted by using the signaling 4 which may be the RRCsignaling. The transmission effect is shown in FIG. 4 when differenttransmission parameters are sent separately by using differentsignalings. The beam switching may be quickly sent by using the physicallayer signaling. However, the RS configuration parameter and the maxlayer number configuration parameter, sent by using the high layersignaling, are just switched after the beams between the two partieshave been switched from the beam 1 to the beam 2 for a long time.Consequently, the switching of the transmission parameters lag behindthe beam switching rate, thereby causing the poor transmission effect. Atransmission effect is shown in FIG. 5 when the method provided by thisembodiment is used. Since X sets of parameter values are sent to thesecond communication device in this embodiment, for example, a basestation may send parameter value sets through the higher layer signalingto a terminal in advance, the switching of the transmission parametersis implemented by just sending the selection indication of one or morebits when the beam switching occurs. As a result, the switching of thetransmission parameters may keep up with the speed of the beamswitching, so that the communication quality is not reduced by themismatch between the beam and the used transmission parameters.

In this embodiment, the selection indication may be informationtransmitted through the physical layer signaling. For example, the basestation sends the selection indication via the DCI. The selectionindication may be an index of the Y sets of parameter values. At thesame time, in this embodiment, the X sets of parameter values sent atone time may be used repeatedly, so that the problem of large signalingoverhead caused by repeatedly sending transmission parameters is reducedcompared with the prior art. Therefore, the method has a characteristicof small signaling overhead.

In some embodiments, before sending the X sets of parameter values, asshown in FIG. 2 , the method further includes:

Step S100, the X sets of parameter values to which the M types oftransmission parameters correspond are determined.

For example, the X sets of parameter values are selected and sent to thesecond communication device according to measurement information sent bythe second communication device. For example, the measurementinformation includes the geographical location of a terminal in a cell,a reference signal and/or pilot signal sent by the base station in thebeam and received by the terminal at the geographical location, and thelike. The terminal measures the signal strength and/or received power ofthese signals and sends the measurement information to the firstcommunication device.

The M types of transmission parameters further include one or more typesof the following transmission parameters: a multiple-input andmultiple-output (MIMO) transmission parameter and a reference signal(RS) parameter. The MIMO transmission parameter may be a parameterrelated to an MIMO transmission. The RS parameter may be a parameterrelated to the transmission and reception of various reference signals.

In an exemplary embodiment, the MIMO transmission parameter includes oneor more types of the following transmission parameters: a max layernumber, a codebook subset (CSR), a codebook (CB) parameter, an uplinksub-band size, and a precoding resource bundling granularity (Bundlingsize).

The max layer number is used for indicating the maximum number of MIMOtransmission data streams, for example, indicating the maximum number ofdata streams transmitted simultaneously in the space where the twoparties are located.

The CB parameter is used for configuring the codebook.

The codebook subset (CSR) is used for defining a codeword in thecodebook and controlling the codebook subset selected from the codebookfor the coding.

The uplink resource block size (UL SB size) is used for defining a sizeof the resource block for an uplink transmission.

The precoding resource bundling granularity is used for defining aresource granularity using the same precoding mode. That is, the datatransmission precoding in the corresponding granularity resource is thesame.

In an exemplary embodiment, the RS parameter further includes one ormore types of the following transmission parameters: a DMRSconfiguration parameter, a PTRS transmission indication and a trackingreference signal (TRS) configuration parameter.

In some embodiments, the DMRS configuration parameter may be a parameterrelated to a DMRS transmission, including frequency domain transmittinginterval and/or time domain transmitting interval of the DMRS. The DMRSconfiguration parameter may further include: transmission resources usedfor the DMRS transmission, where the transmission resources include:frequency domain resources, time domain resources and/or code domainresources.

The PTRS transmission indication is at least used for indicating whetherto transmit the PTRS. For example, in X sets of parameter values jointlyencoding the M types of transmission parameters, 1 bit may represent thePTRS transmission indication. When the value of the 1 bit is a firstvalue, the PTRS transmission indication indicates to transmit the PTRS,and when the value of the 1 bit is a second value, the PTRS transmissionindication indicates not to transmit the PTRS. The first value is notequal to the second value. For example, if the first value is 0, thesecond value is 1; while if the second value is 0, the first value is 1.

In this embodiment, the PTRS transmission may be used for estimating alocal oscillator of an oscillator.

The TRS parameter may be used for indicating information related to thetransmission of the TRS, and for example, may include: a resourcelocation and/or a transmission density used by the TRS transmission andother related parameters.

In some embodiments, the transmission parameters further include one ormore types of the following parameters: a retransmission parameter, aresource allocation parameter, a bandwidth part (BWP) parameter and amodulation and coding scheme parameter.

The retransmission parameter may be used for indicating informationrelated to the data retransmission, and for example, may include: ahybrid automatic retransmission request (HARQ) parameter, an autoretransmission request (ARQ) parameter, or other parameter related tothe retransmission.

The resource allocation parameter is used for indicating resourceallocation state information, for example the resource allocationparameter includes an uplink resource allocation parameter and adownlink resource allocation parameter. The second communication devicemay learn at which resource location the data is sent or received, or atwhich resource location competes with other communication devices forresources according to the resource allocation parameter.

The modulation and coding scheme (MSC) parameter may include one or moreMSC tables which are suitable for the beams which use the MSC after thebeam switching.

In some exemplary embodiments, the step S100 may include: determiningthe X sets of parameter values to which a pilot resource locationreported by the second communication device corresponds.

In an exemplary embodiment, the method further includes:

-   -   Step S121, an acknowledgment message sent by the second        communication device based on the selection indication is        received;    -   Step S120 may include: performing the data transmission with the        second communication device according to the Y sets of parameter        values after the acknowledgment message is received. The data        transmission is performed by using a beam to which the Y sets of        parameter values correspond. Beam identities and beam parameters        of different beams are different. The beam identity may be a        sequence code or name of the beam. The beam parameters may        include a beam bandwidth, a beam direction and a beam        transmitting node.

In some embodiments, only after the acknowledgment message sent by thesecond communication device is received, the first communication devicecommunicates with the second communication device by using the Y sets ofparameter values, thereby avoiding the problem in which the secondcommunication device fails to receive information of the firstcommunication device when the second communication device fails toreceive the selection indication and the first communication device usesthe Y sets of parameter values to communicate and the problem in whichthe first communication device fails to receive the data sent by thesecond communication device when the first communication device hasalready performed the beam switching by using old transmissionparameters to transmit the data.

In other embodiments, before the acknowledgment message is not received,the first communication device uses the currently used transmissionparameter to transmit data with the second communication device.

As shown in FIG. 6 , an embodiment of the present disclosure provides aninformation processing method which is applied to a second communicationdevice. The method includes:

Step S210, X sets of parameter values jointly encoding M types oftransmission parameters sent by the first communication device arereceived, where the M types of transmission parameters include a beamindication and/or a QCL indication parameter, where the beam indicationis used for indicating the beam, the QCL indication parameter is usedfor indicating a parameter of the beam, and M>1.

Step S220, a selection indication sent by the second communicationdevice is received.

Step S230, Y sets of parameter values are selected from the X sets ofparameter values for the data transmission according to the selectionindication, where X>=Y>=1.

In an exemplary embodiment, the method further includes:

Sending a resource location of a pilot signal to the secondcommunication device, where the X sets of parameter values are parametervalue sets to which the resource location corresponds.

The second communication device feeds back the resource location of thepilot signal detected by its own to the first communication device.According to the resource location of the pilot signal, the firstcommunication device may learn which beams currently received by thesecond communication device have the optimum signal quality, therebydetermining the parameter values according to the received resourcelocation of the pilot signal.

In an exemplary embodiment, the method further includes:

sending an acknowledgment message to the first communication deviceafter the selection indication is received.

In order to notify the first communication device that the secondcommunication device has received the selection indication, the secondcommunication device, after receiving the selection indication, sendsthe acknowledgment massage to the first communication device andnotifies the first communication device that the second communicationdevice has successfully received the response message.
